NAME
    MIME::Decoder::Base64 - encode/decode a "base64" stream

SYNOPSIS
    A generic decoder object; see MIME::Decoder for usage.

DESCRIPTION
    A MIME::Decoder subclass for the "base64" encoding. The name was chosen to jibe with the
    pre-existing MIME::Base64 utility package, which this class actually uses to translate each
    chunk.

    *   When decoding, the input is read one line at a time. The input accumulates in an internal
        buffer, which is decoded in multiple-of-4-sized chunks (plus a possible "leftover" input
        chunk, of course).

    *   When encoding, the input is read 45 bytes at a time: this ensures that the output lines are
        not too long. We chose 45 since it is a multiple of 3 and produces lines under 76
        characters, as RFC 2045 specifies: The encoded output stream must be represented in lines of
        no more than 76 characters each.
